A Family-Run Building Company Built on Experience
AJ Building Contractors was founded by Tony Dean and his son, Jack, combining decades of hands-on trade experience with modern site management and compliance expertise.
Tony is a joiner by trade, holding City & Guilds and Advanced City & Guilds qualifications, with more than 40 years’ experience working for a major construction firm, where he progressed to Construction Director. Jack is a qualified Site Manager, responsible for project planning, coordination, and day-to-day site operations.
Together, they formed AJ Building Contractors to offer homeowners access to experienced builders in Anglesey who deliver personal service, consistent quality, and reliable project management, without the shortcuts often seen in larger or less accountable firms.
